WebValue at risk (VaR) measures the maximum potential loss of a given portfolio over a prescribed holding period at a given confidence level, which is typically chosen to be 1% or 5%. Therefore, assessing VaR amounts to estimating tail quantiles of the conditional distribution of a series of financial returns.

Web16 Apr 2015 · We present new measures: bivariate lower and upper orthant Tail Value-at-Risk. They are based on bivariate lower and upper orthant Value-at-Risk, introduced in Cossette et al. (Insurance: Math Econ 50 (2):247–256, 2012 ). Many properties and applications are derived. WebA risk measure ρ is sub-additive if the following is true. ρ(X +Y) ≤ ρ(X)+ρ(Y) (1) Thus, the risk measure of the sum of two assets is bounded above by the sum of their individual 2 risks.1The property of sub-additivity can be motivated by many practical considerations.
